I have noticed a few of you mentioning F500's, 600's, and so on. I have a 64 F750, and it looks like I may have a rear wheel cylinder leaking. How do you get the drum off? Do you have to pull the axle shaft out of the differential to get the hub off, and are the 5 nuts between the hub "spokes" holding the drum on? Looks like allot of work, any and all info is appreciated!

P.S. I think I have the Eaton 2-speed rear axle.

 

I have a 65 F-700 but i haven't dug into the brake system yet...

 

Thanks anyway for replying, I think the brake system on these may be a weak point. Mine is a single reservoir system with a vacuum booster mounted on the frame under the driver's seat.
